Question Look at the photogra:

  • Can you think why Sunita’s hair was standing?

  • Look at Sunita’s photographs and the dates written on each of them. Write what all is happening and when?

Answer:

  • Sunita’s hair was standing in the spaceship as she was very much above the earth. There is no pulling force in the space to make everything come down. Everything floats in the space.
  • Sunita with her other friends started their onward journey on 9-12-2006 in their spaceship. There are two photographs dated 11-12-2006. The first one shows Sunita and her friend floating in the spaceship. The second photograph shows food packets flying in the spaceship. The photograph dated 13-12-2006 shows Sunita’s hair not falling down while she continues with her work with ease. The photograph dated 16-12-2006 shows that Sunita has come out of the spaceship and floating in the space.

    Picture shown

    Globe

    It is a real photograph of the earth.It is a model of the earth.
    There is no division line separating the countries and states.There are division lines separating the countries and states.

 

  • I think Sunita could not have made out Pakistan, Nepal and Burma separately, when she saw the earth from space. This is because she could not see the lines of division between the countries from space.

Question What we have learnt:

  • Why do children always slide down the slide and not slide up? If this slide were there in Sunita’s spacecraft, would children slide like this? Why?
  • Why do we see stars mostly at night?
  • Looking at earth from the space, Sunita said, ”Different countries cannot be seen as separate from here. These lines are on paper. They are made by us.” What do you understand by this?

Answer:

  • Children always slide down a slide because the earth has a very powerful pulling force that always pulls things towards it.
  • The stars are celestial bodies having light of their own. The sun is also a star. It is the closest star to the earth. During the day time we are not able to see the stars because the sun’s light is very bright and it blocks the other stars.
  • When observed from the space, the lines that we see between the countries and states are not visible. These lines that we see on the map are not actually present but are drawn by man for his own convenience.
